I am looking for any info in the Iavarone family from Secondigliano, near Naples.

So far, I have:

Cosimo Iavarone (birth guesstimate: 1861)
Luigi Iavarone, son of Cosimo, born 1881
Luigi's wife, Louise Aiello, born 1881
Luigi (later, Louis) and Louise came to Chicago in 1902.

I am looking for more info on Cosimo, his wife, their kids, or any other info that may help connect the dots.

Thank you! :)
